The CData Power BI Connector for Facebook Ads supports standard SQL joins like the following examples.

Inner Join

An inner join selects only rows from both tables that match the join condition:

SELECT a.Name, d.AccountStatus FROM AdAccounts a INNER JOIN Ads d ON a.Id = d.Target

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

 SELECT a.Name, d.AccountStatus FROM AdAccounts a LEFT JOIN Ads d ON a.Id = d.Target
